Objective To evaluate the correlation between the endolymphatic hydrops in vestibule and symp‐toms ,audiovestibular functions in patients with Meniere's disease .Methods Twenty -four hours after bilateral intra-tympanic 8 times diluted gadolinium administration , three - dimensional fluid - attenuated inversion recovery MRI ,using a three-Tesla unit ,was performed in 34 patients .The extent of endolymphatic hydrops in the MRI images was assessed and compared the hydrops with age ,duration ,stage of the disease ,frequency of attacks ,pure tone audiometry ,caloric test ,electrocochleography and vestibular evoked myogenic potentials .Results Thirty -four patients showed different levels of enhancement of perilymth in the inner ears .In these patients ,obvious signs of endolymphatic hydrops were visualized ,including 8 slight hydrops ,11 mild hydrops and 15 significant hydrops . In all 34 patients ,the results of PTA were 9 dB HL to 90 dB HL ,with average of 43 .56 dB HL and there were 21 abnormal and 13 normal patients in caloric test with a diagnostic rate 61 .76% ;17 normal ,7 abnormal and 10 not elicited patients in VEMP with a diagnostic rate 50% ;22 abnormal and 12 normal patients in electrocochleography with a diagnostic rate 64 .71% .There were almost no complications in all 34 patients after bilateral intra-tympanic injec‐tion except short vertigo among 5 of them .A statistically significant correlation was found between degrees of en‐dolymphatic hydrops in vestibule and age ,stage of the disease and VEMP (P<0 .05) ,whereas no significant corre‐lation was found between the extent of endolymphatic hydrops and duration ,frequency of attacks ,pure tone audi‐ometry ,caloric test ,electrocochleography(P> 0 .05) and the correlation coefficient were 0 .494 ,0 .568 ,0 .590 , 0 .495 ,respectively .Conclusion The degree of endolymphatic hydrops in Ménière's disease has significant correlation with age ,VEMP ,stage of the disease and pure tone audiometry .No significant correlation was found between hy‐drops and duration ,frequency of attacks ,functional level scale ,caloric test and electrocochleography .

Thyroglossal duct cyst and fistula is one of the most common birth defects. Thyroglossal duct carcinoma occurred in residual thyroglossal tube or thyroglossal duct cyst is a rare disease which is often difficult to diagnosis by clinical examination, and the prognosis by surgical removal is good. We present a 29-year-old female with thyroglossal duct cyst. In our case, the patient underwent thyroglossal duct cysts dissection without systemic preoperative examination for thyroid. Histologic analysis after a Sistrunk procedure revealed a small focus of papillary carcinoma within the TGDC. The patient has been followed up for 1 years without any metastasis.

OBJECTIVE: To evaluate the extent of endolymphatic hydrops as shown by three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging (3D FLAIR MRI) performed 24 hours after bilateral intratympanic gadolinium administration and discuss the positive rate of endolymphatic hydrops in vestibule and cochlea. METHOD: Twenty-four hours after bilateral intra-tympanic 8 times diluted gadolinium administration, three-dimensional fluid-attenuated inversion recovery MRI, using a three-Tesla unit, was performed in 48 patients, and then assessed the extent of endolymphatic hydrops in the MRI images. RESULT: Forty-eight patients showed different levels of enhancement of perilymth in the inner ear. In these patients, obvious signs of endolymphatic hydrops were visualized in vestibule,including 8 slight hydrops, 17 mild hydrops and 23 severe hydrops with a diagnostic rate of 83.3%. There were almost no complications in all 48 patients after bilateral intra-tympanic injection except short vertigo in some of them. CONCLUSION 3D FLAIR MRI resonance imaging has a high positive diagnostic rate in assessing endolymphatic hydrops of Ménière's disease and provides direct imaging evidence for diagnosing Ménière's disease.
